Common NameTris(2-chloroethyl)phosphate
ClassSmall Molecule
DescriptionTris(2-chloroethyl) phosphate (TCEP) is a chemical compound used as a flame retardant, plasticizer, and viscosity regulator in various types of polymers including polyurethanes, polyester resins, and polyacrylates. It was included in January 2011 in the European Chemicals Agency (ECHA) list of Substances of Very High Concern (SVHC) due to its being toxic for reproduction. Substances in the list of SVHCs are those for which ECHA is considering imposing a requirement for authorization for some or all uses.
